UNITED STATES PATENT QFFT CHARLES FRIBERG, OF EL PASO, TEXAS.

DOOR-BRACE.

To all whom it may concern:

Be it known that 1, CHARLES F RIBERG, a citizen of the United States,residing at El Paso, in the county of El Paso and State of Texas, haveinvented certain new and useful Improvements in Door-Braces, of whichthe following is a specification.

My invention relates to new and useful improvements in door braces.

The objects of my invention are to provide an adjustable brace tostrengthen and reinforce the frames of doors, gates and the like, and atthe same time prevent and remedy their sagging or striking either theframe or door-sill, or dragging on the floor, and which can be used onsolid, skeleton or screen doors, and on either the right or left side ofthe same.

iVith these objects in view, and others which will appear from thespecifications and claims, my invention consists of the several detailsof construction and combination of parts hereinafter fully described andparticularly pointed out in the claims.

In the accompanying drawings, which are made a part of thesespecifications, Figure 1, is a front elevation of a door with asectional view of the brace attached thereto. Fig. 2, is a detail viewof the bar member. Fig. 3, is a front elevation of the base plate. Fig.4t, is a side elevation of the same plate. Fig. 5, is a sectional sideview of the base plate and adjusting bolt, adapted to each other.

Referring specifically to the drawings, 1, is a longitudinal section ofan ordinary door, to which the hinges are attached, and at its junctionpoint with the lower transverse section, 2, of the same.

3 is substantially a T shaped base plate, provided with lateral flanges,4- 1, extending outwardly at right angles to the main body of the plate,and reinforced by braces or brackets, 4:-t. Each flange is provided witha central opening, 5, adapted to the passage of an adjusting bolt, ashereinafter detailed. The base plate has suitable openings, 66, for thepassage of screws by which it is attached to the longitudinal section ofa door, or gate; and also an opening, 7, at the extremity of the T arm,adapted to 'pivotally engage a bar attached to the trans verse sectionof the door. On the rear surface of base plate 3, are provided smallprojections or lugs, 8-8 which penetrate the surface of the door as thescrews 6-6, are

forced into the wood. These lugs are de signed to give stability to thebase plate, but are not essential to the successful operation of thebrace, and can be abandoned when at tached to hardwood doors, as thescrews, 66, are suflicient to solidly retain the base plate under theseconditions.

9 is a bar provided with an opening at one end, at 10, through which ascrew, 10, may be inserted attaching itto the transverse section, 2, ofthe door; its other end is pro vided with a like opening, 11, adapted toengage the curved end of an adjusting bolt 12, in the operation of thedevice. Approximately in the center, longitudinally of this bar, 9, is athird opening, 13, where it is pivoted at let to the base plate 3 at theopening 7 in the same.

12 is a bolt sufficiently curved at one end, 15, to permit its entranceand engagement in opening 11 in bar 9 as the bolt is vertically insertedin opening 5 in flange 4 of the base plate 3. The otherend of the bolt12 is threaded and adapted to a nut 16, provided for the purpose ofraising or lowering the bolt in adjusting the mechanism of the brace.

Each flange, 1, of the base plate 3, is provided with an opening, as at5, to receive bolt 12, thus suit-ing the plate to either the right orleft side of the door, thereby producing a reversible brace.

From this description it is obvious that the operation of the severalparts of my invention in combination, is as follows :-The base plate 3,being attached to the longitudinal section 1, of the door, where thehinges are fitted, and preferably near the bottom, at the intersectlonwith the trans verse section of the door, 2, by means of screws 66, theflanges t- L, extending outwardly, and the arm so located as to extendover on the transverse section of the door. Bar 9 is pivoted at 14, tobase plate 3 through the opening 7, and extends horizontally along thetransverse section where its outer end is attached by screw 10, itsother end passes centrally over base plate 8, in such manner thatopening 11, is vertically above opening 5 in flange 4 of the base plate.The threaded end of bolt 12 is passed through opening 5 of flange 4, andits curved end, 15, adjusted to opening 11 in bar 9; nut 16 is thenscrewed on the threaded end of bolt 12, as it extends through opening 5sufficiently to permit the use of the nut.

By the manipulation of nut 16, bolt 12 is raised or lowered as desired,and this reciprocating motion of the bolt, operating in and engagingopening 11 in the bar 9, elevates or lowers the bar, causing theopposite end attached by screw 10 to the transverse section 2, of thedoor, to respond to the action, and as bar 9 operates pivotally at 14,as the end over base plate 3 is elevated the other end lowers, or if itis lowered the other end is raised, thereby causing the entire frontportion of the door to coact with the transverse section to which bar 9is securely attached. This manipulation removes the door sag andprevents contact with the frame or sill, and at the same time closesdisconnected joints and loose connections. In the same manner the bracemay be used on new doors to prevent warping and sagging, and also toreinforce and strengthen the various parts.

Having described my invention, what I claim, and desire to secure byLetters Patent, is 1 1. In an adjustable brace, a base plate adapted tobe secured to a door or the like, having. lateral flanges bent outwardlyat right angles to the main body and reinforced by braces, each flangeprovided with a central opening, in combination with a bar withapproximately central and end openings,

one end adapted to be secured to a door the other end engaging anadjusting bolt, and centrally pivoted to the base plate; an adjustingbolt, curved at one end to enter and engage an opening in the bar, theother end being threaded and adapted to be inserted in an opening in theflange, and provided with a movable nut, substantially as and for thepurposes described.

2. The combination with a door of a reversiblo brace, adjustable in itsparts, comprising a base plate adapted to be secured to a door andhaving lateral outwardly eX- tending flanges provided with centralopenings, and lugs on the rear of the base plate; a bar withapproximately central and end openings, and .adapted to pivotalattachment to the base plate; an adjusting bolt curved at one end andthreaded at the other adapted to vertically engage said bar and anopening in a flange on the base plate, and a movable nut on the threadedend of the bolt abutting the lower surface of a flange on the baseplate, substantially for the purposes described.

In testimony whereof I afliX my signature in presence of two witnesses.

CHARLES FRIBERG.
